After searching online, I found that the error occurs when you try to call a string as a function and can be resolved by changing the module name. However, even after changing the module name many times, the error continues to occur in module Resume() in the "else" when running program. Unable to resolve the error even after changing the function name. Please advise.

CodePudding user response：

This is because in the Resume function you defined a variable named Resume:

def Resume():
    # They have the same name!
    Resume = input("Do you want to continue playing (Yes/No)? ")

So, once you define that variable, Python thinks that the name of variable "Resume" is referring to that string. After that, in your else section, you're using that name as a callable, just like a function, but turns out its a string now:

    else:
        print("Invalid input. Only \"Yes\" or \"No\" is allowed (Case sensitive). Please try again.")
        Resume()  # This is actually a string!

You should rename that variable to avoid conflicts with the original function name.

A possible solution (rename user input variable to keep_playing):

#To determine whether to resume
def Resume():
    keep_playing = input("Do you want to continue playing (Yes/No)? ")
    print("\n")
    if keep_playing == "Yes":
        Level()
    elif keep_playing == "No":
        print("Exiting...")
        exit()
    else:
        print("Invalid input. Only \"Yes\" or \"No\" is allowed (Case sensitive). Please try again.")
        Resume()

I ran your code and was able to get the same error TypeError: 'str' object is not callable

In my case, I saw that the call tot he Level() function was indented when it should not be indeed. As it is, you are calling the level function within the Level() function itself, as if it is a recursive function.

I simply moved the call to the Level() outside the function.

Also, I noticed that after moving the Level() function, you are calling that function twice, once right after the Level() and once in the last line of code.

Hope this was the fix you were hoping for.
